Abstract: The present disclosure relates to a metal air filter including: a filter which is formed of a metallic material by electrodeposition and has a nano branch structure; an ionizer which conducts particles to be captured by the filter with negative charges; and a power supply which supplies a positive voltage for conducting the filter with positive charges and a negative voltage for the ionizer. The filter can be more simply manufactured at a lower cost than a conventional process.
